In this discussion I am going to explain all the tactics and tools that helps you to optimize the images.
I have seen that some of the bloggers are taking advantage of this image optimization and driving huge traffic to their website and making money from AdSense. This mostly happen when there is a festival seasons. They just create some images related to those fest and correctly optimize them and post it to their website.
So here you can see the power of image optimization and ranking in image search.
Today I am going to show you various tactics for optimizing images on your website.
How Google ranks images?
When you compare both indexing natural text post and images, it is much more difficult for search engines to index images. Because Google is not capable of understanding what’s in the images. But Google has some clues to find the content on the image. Google is known to be experimenting with artificial intelligence algorithms to improve detection of content on images.
Search engines are now experimenting with OCR (Optical character recognition) to read text on documents. But most of the times images don’t have text to read, In that case Google uses facial recognition method to know who’s in the image.
In this similar way Google has its own ways to find and understand the images.
Image optimization tips:
Let’s start looking at ways to optimize your images.
- Make sure the image file name or img src contains your primary (main) keyword. If it is an image of Google, name the file as Google.jpg and upload it to your website. The image path will looks like https://www.searchenginecall.com/google.jpg.
- You must use the image alt attribute. The search engines will have a better idea of what your image is all about when you add an alt attribute. The format of writing the HTML code to insert alt attribute is :
<img alt=”Google image” src=”https://www.searchenginecall.com/google.jpg”/>
- Give a title attribute to the image. Title attribute is used for both search engines and users. The image description will appear when a user hover over to the image.
<img alt=”Google image” src=”https://www.searchenginecall.com/google.jpg” title="Google Image">
- Use quality images. Because Google is not going to rank low quality images. So make sure images are high in quality and low in size. This can be achieved by compressing the image sizes. If you are using the adobe Photoshop you’ll have an option “Save for Web”. By this you can reduce the image size without losing quality of image. There are some online tools available to do so, site like tinypng.
- Keep your images as close as possible to the root domain. I mean that put your images by the next level of folder. For example upload the image to https://www.searchenginecall.com/google.jpg instead of uploading to https://www.searchenginecall.com/content/images/20/11/25/google.jpg.
- Don’t use the images that are subjected to copyright. Use only original images or at least make some modification to the images. If you take an image from any public domain and needs credit for the author ‘just give the credit’. There no need to afraid to giving a credit to author if you are using his images.
- Create a separate site map for the images and submit it to Google in Google Search Console.
- If you are using the WordPress and if you don’t have time to optimize all the images separately use the plugin https://wordpress.org/plugins/seo-image/ . This plugin does the all work you need. But remember it is another plugin you are installing on your WordPress site which may affect site loading speed.
